Problems with installation Report extensions

Hi all!
Please help me with installation of Report extensions!
I followed by Readme file:
1. Unzip SlkReportExtension.zip to a directory in machine with WSS installation, say c:\install.
2. Modify Deploy SLK Report Extension.bat to point WebAdminSitePath, WebSitePath, and LearningKitSitePath path to proper folders.
3. Execute the batch file.
How should i manually update my SLK’s sitemap to make the report site show up in SharePoint’s breadcrumb? What file is it?
And after that how should i Change database in SQL to SharepointLearningKit ?
Please, write me more detailed instructions, who installed it before!
Thank you!
